Beta 2: Blinking menu text

Occasionally, I see some text, such as menu text, quickly blinking?
Has anyone else seen this behavior, and is there a workaround? I've
tried reducing the colors from Millions to Thousands, and down to
256. This problem doesn't present in Version 1, but we need version 2
for printer sharing from Intel Macs.

In most cases, closing the connection and reconnecting fixes the
problem. This happens on Windows Server 2003 and Windows 2000
Terminal Server.
